WIN snow,

Illinois, have invented a certain new and usefullmprovement in Windows, of which the following is a full, clear, concise, and

exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to an improved construction of window and is concerned with certain structural features for securing eflie cient weather-pints and forsecuringin general a sturdy, simple, and easily manipulated window.

to engage the masonry of the building. The channel section 1 has secured across its inner face at the top of the window-frame an angle bar 2 to'serve as a stop for the upper sash 3 to close the joint between the sash and the frame to exclude rain and cold. The lower ortion of the frame is of such conformation that an upwardly extending.

flange 4 is provided to enter between the members 5 and 6 of the lower rail of the lower-sash 7. The upper surface of the bottom of the window-frame is inclined downward, as indicated, to shed the water which drops upon-it from the lower sash and, if-

spray should be projected into the air-chamber between the members 5 and 6 and the flange 4, it will drain into the inner surface 8 of the bottom of the window-frame which is. curved upwardly, as indicated, and be caused thereby to flow through the drainage openings 9 into the outer part of the windowframefand thus away from the inside of the building. The members 5 and 6 are made a snug fit against the flange 4 so that it is with diffi'cultythat any spray would be projected throughthe joint. The side members of the window-frame are of channel construction, as indicated in Figs. 3 and 4, and have formed longitudinally therein in their exposed faces. shallow grooves for receiving channel bars of special conformation, as indicated at 10 and 11 in Figs. 3 and 4, the

open sides ofthe channels being toward the outside of the room for the upper half of the window and directed toward theroom for the lower half of the window.

The lower sash 7 is formed of vertical channel sect1ons 12 and 13, so made that the: outer flanges enter the "channels in the chan nel bars 11 when the lower sash is closed and I the outer flanges of the channel bars 11 enter the channels in the channel bars 12 and 13, the conformation of the parts being. such that for the closed position of the sash each channel bar engages the bottom'of the channel which it occupies. The upper rail of the lower sash is formed of a channel section .14

open toward the outside of the building to receive the outer' flange of a'ch'annel section 15 constitutin sash 3. The c annel section 15 is-provlded with a downwardly extending outer flange I "16 which engages the outer surface of thechannel section 14 immediately "above the the lower rail of the upper,

glass 17. The channel sections 14 and 15 are so conformed that a considerable air space 18 is left between them, thus permitting free eX-.

pansion and contraction of the metal parts without. changing the closeness of the fit of the weather joints. It will be noticed that the upper rail 14 of the lower sash and the lower rail 15 of the upper sash engage each v other at three points thus making it practically impossible for the weather to beat in from the outside of the window into the 'room. The members 5 and 6 constituting the lower rail of. the lower sash also form between them a considerable air space 19 and .the top 'rail of the upper sash is made of metal sections which inclose aconsiderable 1 air space 20, which air spaces are of great Itis not essential that air spaces be provided between the channel bars 10 and the channel bars 26 and 27, or between thechannel bars -11 and the channel bars 12 and 13, since the.

:deep interlock between these sections pro- Wides that the window could not be twisted or warped clear of the frame by the application of heat. If for anyreason air spaces are desired at the sides of the shell, they may easily be provided by increasing-the sizes of thef'channel sections just referred to,"which will, of course, reduce to a certain extent the 35 size of the glass for a given slze windowframe. I

The side members26 and 27 of .the upper sash areformed in a manner similar to the side members 12 and 13 of the lower sash, the diflerence being that the open sides of the channel are faced inward instead of outward. \Vhen the two sashes 3 and 7 are of about the same height, as is' usually the case, the joints between the upper channel sections 10 and the lower channel sections-11 occur at about the middle of the vertical sides of the windew-frame 1 and, at that point, the outstanding portions of the channel bars are cut away to'receive a washer'21, which forms a support for the stud 22 used to form the pivot of. the lever 23. mounted upon each side of the window and its ends are connected by bolts 24 and.25 with the upper and lower sash, respectively, the lever arms between the pivot 22 and the pins 24 and25 being equal. .The pivot bolt 22 and the washer 21 are preferably of bronze and the ,bolts,24 and 25 are .threaded into bronze bushings 28 and 29, which form "the bearing surfaces within the lever 23, so that the wear- 'ingsu'rfaces are bronze against iron or steel throughout and thus the possibility of the joints freezing as a result of rusting of the ironis avoided. Washers 30 and 31 are provided between the 'lever 23 and the chan- One of these levers is 'above will be more readily lower sash inward a sufiicient that the two sashes clear each other before 'nel bars'27 and 13 for the same purpose. v

almost wholly Within the channels formed in these bars, thus presenting a comparatively unbroken surface on the inside of the build ing up to nearly the middle of the upper sash.

The upper sash 3 has secured to the ends of'its upper rail, as indicated more clearly in Fig. 1, two rollers 32 which project around the backs of the channel bars .10, thus holding the upper ends of the channel bars 26 and 27 of the upper sash. securely in engagement with said channelbars 10. The rollers 32 are preferably of bronze and their rolling action results in comparative ease of operation when the sash is opened or shut and the further advantage also that the paint or enamel on the backs of thechannel bars 10 wi1lnot be injured as would be the case if solid pins were used instead of said rollers.

The lower sash has mounted upon its bottom rail two bronze pins 33, as more clearly shown .in Fig. 4, which normally project so as to lie just outside of the backs of the channel bars 11, as a result of which the lower ends of the-channel bars 12- and 13 of .the lower sash are held securely in engagement with said channel bars 11. .The pins 33 are slidably mounted in housings 34 secured to thelower rail of the lower sash, springs being provided in the housings to hold the pins in place. The pins 33 are extended through the housings 34 into finger holds 35, by which the pins may be withdrawn from back of the channel bars 11 when it is desired to swing the lower sash into the room away from the channels 11 so that the outer surface of the glass 17 may be washed. When the sash are in closed position, the lower rail of the upper sash and the upper rail of the lower sash are clamped together by means of the cam 36, pivotally mounted at 37 upon a bracket 38 secured to the upper v rail of the lower sash, which-cam 36, engages a catch 39 carried by the lower-rail of the upper sash in such a manner that the cam surface moves the two i'ails laterally into tight clamping engagement when the cam is moved upon its pivot 37. This action is more clearlyshown in Fig. 9.

The.operation' of the device described understood by reference to Fig. 10. When the window is shut the two sashes are in vertical position, as are also the balancing levers 23. ,When it is desired to open the window, the catch 36 is released and, by moving the bottom of the. upper sashoutward, the levers 23 being pivotedto the frame 1, force the top. of the amount so the rotation of the levers 23 cause any vertical motion of the sashes. Continued motion of the levers 23 in the same direction causes the upper sash to be lowered and the lower sash to be raised, which operation may continue until the upper sash rests against the lower sash and is practically at the same height as the lower sash, as'indlcated in dotted lines in Fig. 10, which position is the one assumed by the sashes when the window is wide open. It is apparent that the sashes may be left in any intermediate position that is desired and, since any wind that may be blowing exerts equal and opposite thrusts upon the two sashes, .these forces are exerted upon the supporting levers in opposite directions and, as a result, there is no motion of the sashes either toward their. open ortoward their closed positions. It will be further observed that when it is desired to open the window but a small amount that the middle rails of the sashes may be separated somewhat without perceptibly changing the position of the upper rail of the upper sash and the bottom railof the lower sash, which condition is particularly desirable when ventilation is necessary, but it is undesirableto permit a large quantity of cold air to enter the room.

In order to swing the upper sash 3 into the room, 'for cleaning the outer face of the clined upper and lower ends which fit the glass mounted therein, provision is made to remove a portion of the channel bars 10 as follows: The portion of the bar, as shown at 10* in Figs. 8 and 10, is provided with inadjoining ends of the main channel bar 10, such portion 10* being removably held in place as followszThe lower end of the section 10" is provided with a bolt '40 which extends through the channel section 1 and Q has mounted upon it between. said channel section 1 and its head 41 a spring 42, which normally exerts a thrust upon the section 10 holding it into the longitudinal groove 1 formed in the web of the channel section 1. Y The upper end of the section 10* is provided with a lug 43 extending through the channel section 1, which lug has formed therein an opening adapted to be engaged by a taper pin 44, as shown in Fig. 3., The engage-- ment between the lug 43 and the pin 44 holds the upper end of the section 10 in the channel formed in the web of the window-frame section 1. The bolt 41 andthe lug- 43 are surrounded by housings 45 and 46 to protect them from the masonry builtinto'thel channel section 1 between its flanges. To lower the upper sash 3 into the room for cleaning purposes, the window, is first opened a suflicient amount so that the section. 10 may bemoved from its normal position. Then the taper ins 44 are drawn out, their removal from t e channel section 1 being prevented by lugs orpins 47 projecting .so-called transom? eflfect.

therefrom. Then the upper end of the section 10 is forced out of engagement with the channel section 1 a suflicient amount to clear the lug 43 fromthe said section 1, and the section 10 is turned against the action of the spring 42, so that it occupies the position indicated in dotted lines in Fig. 10. Then,

the window is opened farther, so that the upper end of the upper sash comes below the fixed portion of the channel bar 10, and

when in this position the upper end of the upper sash may readily be moved into the room until it' rests upon the inturned section 10 of the channel bar 10.

The upper rail of the upper sash has mounted thereon, as indicated, a spring roller 48 for supporting a shade 49. The lower edge of the shade is secured to a crossrod or bar 50, from which a cord 51 extends downward through an eyelet 52 secured to the lower rail of the upper sash, from which I eyelet the cord passes upward around the outside of the shade on the roller '48 and down to the cross-bar50, where it is secured to the upper end of the cord 51, thus making acontinuous belt through the eyelet 52 and around the roller 48, which positively holds the shade 49 in any position to which it may be adjusted without permitting it to sag or flop when the sash is movedto an in clined position, as indicated in Fig. 10. The

lower sash is similarly provided with aroller 53 which supports a correspondingshade in a similar manner on the inner surface of thelower sash. The cross bar50 may have a screw-eye inserted into it at about its middle position, or the ends of the cord may be joined through an eyelet inserted through the central ortion of the bar, as desired.

While I have shown and described above a'window in which the sashes are of substantially the same size, my invention is not limited to this proportion, since the uppersash may, if desired, be of much less height than the lower sash, in order to secure the For this construction, theparts will be so proportioned that the supporting levers would operate the upper sash in the same manner as though both sash were of the size of the upper sash, thus bringing the upper sash to a position so that its top is substantially alined with the top of the lower sash when the window is wide-open. For this arrangement,-in order exact construction shown without departing from the spirit of my invention. v

What I claim is: 1. In combination, a window frame, an

upright channel member on each side of the frame, a pair of swinging sashes mounted therein and having a channel member on each side thereof arranged tointerlock with said upright channel members, said sashes swinging in opposite directions about their own respective pivots, the bottom .Of the upper sash being in the form of a channel member and the top of the lower sash being in the form of a channel member, said channel members being arranged so that theirflanges interlock when the window is closed,

the flanges of each channelcontactin with the opposite channel to form a plura ity of tight weather joints at such' time.
